Corns and calluses are protective mechanisms of the skin that form in response to pressure and friction. They frequently manifest on the feet, often due to walking or wearing improperly fitting footwear. Corns present as small, distinct circles typically located on the tops and sides of the toes, whereas calluses tend to develop on the soles of the feet, particularly under the heels or balls. Although both can cause discomfort or pain, particularly under pressure, they are manageable and preventable conditions.
